The `site-repl-*` prefix alone classified any rule as site-owned, so on a
bucket outside site replication an owner's `site-repl-user` rule survived
DeleteBucketReplication (rule and target kept, success returned). Rule ids
do not reserve that namespace.
A rule is reconciler-owned only when it matches what the reconciler
derives: id `site-repl-<deployment id>` for a current remote site
replication peer and a destination ARN naming that same deployment id.
The S3 put/delete path reads the remote peer set (empty when site
replication is disabled) and keeps exactly those rules; everything else
is operator state the request replaces or deletes. An incoming rule that
claims a current peer's id is dropped so the reconciler rule's id stays
unique. The peer ingestion path and the reconciler keep their prefix
predicate unchanged.
Under site replication a user holding only bucket-scoped
s3:PutReplicationConfiguration could rewrite or erase the operator-managed
site-repl-* rules, with the change broadcast to every peer (backlog#1948,
audit A1/P2-17).
- Gate PutBucketReplication/DeleteBucketReplication in the S3 handlers:
when site replication is enabled and the requester is not the owner,
return MinIO-parity XMinioReplicationDenyEdit (HTTP 400). The gate runs
after policy authorization and only on the external S3 path; the
reconciler and peer bucket-meta ingestion are unaffected.
- Defense in depth in the bucket usecase: PUT merges the incoming config
with the stored site-repl-* rules (same merge as peer ingestion) instead
of overwriting verbatim; DELETE keeps the site-repl-* rules and never
garbage-collects a bucket target a surviving site-replication rule still
references.
- Move is_site_replication_rule / merge_incoming_replication_config /
replication_target_arn_deployment_id from the admin site-replication
handler down to rustfs-replication so the app layer can reuse them
without new layering violations.
* fix(admin): align replication-reset responses with madmin ResyncTargetsInfo shape
The replication-reset and replication-reset-status responses serialized
their shell as "Targets" and per-target fields in PascalCase, while
madmin-go ResyncTargetsInfo/ResyncTarget expect the "target" shell key
and lowercase field tags (arn/resetid/resyncStatus/replicationCount/
completedReplicationSize/failedReplicationCount/failedReplicationSize).
Go json decoding is case-insensitive per field, but Targets vs target,
Status vs resyncStatus and the size/count key names cannot match, so
mc replicate resync decoded empty results.
Rename the serde tags to the exact madmin wire shape, keep the
ResetBeforeDate/Error RustFS extension keys (unknown keys are ignored
by Go decoders), pin the shape with a snapshot unit test, and update
the e2e client DTO to decode the madmin shape.
* fix(admin): stream bare madmin DiffInfo documents from replication diff
POST /v3/replication/diff returned a single enveloped object
({Entries, IsTruncated, ScannedVersions}) while madmin-go
BucketReplicationDiff decodes the body with a json.Decoder loop over
bare DiffInfo documents. The envelope decoded as exactly one DiffInfo
with an empty object, so mc replicate diff printed a phantom empty row
instead of the real backlog.
Emit one DiffInfo JSON document per line by default, using the exact
madmin json tags (object/versionId/rStatus/deletemarker/lastModified;
Size stays as a RustFS extension key that Go decoders ignore). The
enveloped shape moves to the opt-in ?aggregate=true RustFS extension,
which remains the only carrier of scan-coverage metadata; a truncated
default-mode scan is surfaced via a warn tracing event instead of
in-stream. Pin both shapes with unit tests and tighten the e2e helper
to reject any envelope in the stream.
* feat(replication): validate replication config structure before persisting
PutBucketReplication accepted structurally invalid configurations that
MinIO's replication.Config.Validate rejects: empty or oversized rule
lists, duplicate or negative rule priorities, over-long rule IDs,
filters carrying more than one of Prefix/Tag/And, and delete marker
replication enabled on tag-filtered rules. Such configs persisted
silently and later produced undefined routing (e.g. ambiguous priority
ties) instead of failing the PUT.
Add validate_replication_config_structure as a pure function in
rustfs-replication (limits documented as constants), surface it through
the ecstore api facade, and run it first in the PUT capability gate so
defects are named before any metadata write. Missing Priority counts as
zero for the uniqueness check, matching Go's zero-value semantics. The
self-target rejection deliberately stays at set-remote-target, where the
endpoint is known; a config can never reference a self-pointing ARN.
Document the rule-level Destination.StorageClass contract (use the
remote target's storage_class instead) and renumber the acceptance
matrix e2e to unique priorities, which MinIO would also require.
* test(replication): pin duplicated wire types with boundary reconciliation tests
rustfs-filemeta (xl.meta disk format) and rustfs-replication (MRF/resync
persistence format) deliberately each own ReplicationStatusType,
VersionPurgeStatusType and ReplicationState; the boundary converts
between them via as_str(), whose From<&str> impls fall back to Empty on
unknown tokens — a variant added on one side silently degrades to Empty
on the other.
Add reconciliation tests in replication_filemeta_boundary: exhaustive
matches with no wildcard arm on both sides of both enums (a new variant
fails compilation until the mapping is reconsidered), string-token
round-trip asserts (a token the other side does not recognize fails
instead of quietly becoming Empty), and a full-field ReplicationState
round-trip. Cross-reference the tests from both type definitions.
Struct drift was already compile-guarded by the exhaustive struct
literals in the conversion functions.
* docs(replication): define split completion criteria and milestone sequence
The ecstore replication split plan had no completion measure — the
boundary scaffolding risked ossifying because nothing said when the
migration counts as done. Record the criteria in the module inventory:
done means the Required Contracts table's 'Current dependency to
remove' column is empty; the end state moves pool/resyncer/state into
crates/replication, with the boundary micro-files dissolving as code
crosses the crate line (batch-merging them beforehand is explicitly
rejected — the guard scripts anchor on their file names, so merging is
churn with zero functional gain; only datatypes.rs can retire early).
Sequence the remaining work as M2 (resyncer pure decision logic, after
the oversized function splits) → M3 (worker runtime, highest risk,
last) → M4 (retire boundaries and guard entries). Refresh the stale
first-step text — the event sink / runtime contracts already landed —
and update the split-plan status table accordingly.
* fix(replication): align structural validator with MinIO semantics after adversarial review
Three interop corrections found by adversarial review of the new
structural validator, plus review fallout fixes:
- Delete-marker replication is now rejected only for a direct Filter.Tag,
not for tags inside Filter.And — MinIO's validator only inspects the
direct tag, and mc replicate add --tags "k1=v1&k2=v2" (delete-marker
replication on by default) puts multiple tags into And.Tags, so the
stricter check rejected mc-generated configs MinIO accepts.
- Rule ID length is measured in bytes (Go len semantics), not chars —
a 255-char multibyte ID must not round-trip into a config MinIO
rejects.
- An empty <Tag/> element (no key) counts as absent, matching MinIO's
Tag.IsEmpty(); console form serializers emit empty tags, which would
otherwise trip the exactly-one-of and delete-marker checks.
Also: repair the store-uninitialized PUT test whose empty-rules fixture
now (correctly) fails structural validation before reaching the store
lookup; pin the previously untested startTime madmin key in the
reset-status shape test; and signal a truncated default-mode diff scan
via the x-rustfs-replication-diff-truncated response header — the bare
madmin stream has no envelope, so a truncated scan was otherwise
indistinguishable from a complete healthy one (madmin/mc ignore unknown
headers).
* test(e2e): activate SSE-S3 replication contract and pin resync fail-closed path
The SSE-S3 replication contract e2e was ignored under backlog#1291
(silent plaintext replication); the fail-closed gate in
replication_target_boundary.rs closed that hole, so the ignore reason
expired. Un-ignore the test — it now pins the current fail-closed
contract (FAILED status, failure event, readable encrypted source,
stable absence of all target versions), verified green.
Add test_bucket_replication_sse_s3_resync_stays_fail_closed: drives the
existing-object resync path (PUT ?replication-reset) over a FAILED
SSE-S3 object and asserts the resync generation reaches a terminal
state without ever materializing a target version, with the
stays-absent window also spanning fast-scanner heal cycles. The new
start_bucket_replication_reset helper doubles as the madmin
ResyncTargetsInfo shape assertion (target[0].arn/resetid) for the
reset-start response.
Refresh the stale nextest count commentary (the module is at 20 fast +
36 nightly = 56 tests by cargo nextest list; the SSE-S3-ignored note no
longer holds).
* test(replication): accept madmin nanosecond healthCheckDuration payloads
Red-phase TDD tests for P0-7: mc 'replicate add' sends the madmin default
healthCheckDuration=60s as a Go time.Duration nanosecond integer
(60000000000), which RustFS currently rejects as an unsupported field and
would misread as seconds. Also pins the defensive seconds-or-nanos read
for persisted bucket-targets metadata and the capability contract listing
healthCheckDuration as writable.
Currently failing (red):
- remote_target_request_accepts_go_duration_wire_values
- remote_target_request_accepts_legacy_seconds_health_check
- remote_target_health_check_duration_is_declared_writable
- bucket_target_reads_go_nanosecond_durations_defensively
- runtime_capabilities_response_reports_missing_topology_before_storage_init
* fix(replication): accept remote target healthCheckDuration nanoseconds
mc 'replicate add' always sends the madmin default healthcheck-seconds=60
serialized as a Go time.Duration nanosecond integer (60000000000), so the
default mc link-creation path (and 'mc replicate update') failed with
InvalidRequest. Move healthCheckDuration from the unsupported to the
writable remote-target field list; the capability contract in the runtime
capabilities response follows the constants automatically.
Fix the unit mismatch in both directions:
- Request parsing and persisted bucket-targets reads decode the value
defensively: below 10^7 it is legacy RustFS seconds, otherwise Go
time.Duration nanoseconds (also covers MinIO-written metadata).
totalDowntime shares the same wire shape and gets the same handling.
- The list-remote-targets admin response re-encodes only these two fields
as nanoseconds via a dedicated serialization path, leaving the persisted
seconds-based wire format untouched for existing readers.
The per-target health-check interval is accepted for mc compatibility but
not yet applied; the heartbeat keeps its global env-configured interval,
and the explicit 'healthcheck' update op stays rejected. disableProxy,
edge, and edgeSyncBeforeExpiry remain explicitly rejected.
* fix(replication): accept explicit STANDARD destination storage class
The replication engine never reads Rule.Destination.StorageClass (replica
placement comes from the bucket-target config or the source object), yet the
validator rejected any config carrying the field. The console's add-rule form
always sends StorageClass=STANDARD, so every rule created through it failed
with InvalidRequest.
Tolerate exactly STANDARD as a no-op — semantically identical to omitting
the field — and keep rejecting every other value, which would be silently
ignored rather than honored. Document the deliberate omission from the
replication capability contract.
* feat(admin): support MinIO-style partial updates for set-remote-target
set-remote-target?update=true previously replaced every stored field and
required complete credentials in the body, so flipping a target's sync mode
from the console forced operators to re-enter the secret key, and real
mc replicate update bodies (madmin Clone() strips the secret) failed to
deserialize at all.
Adopt MinIO's TargetUpdateType contract: query params creds/sync/bandwidth/
path name the field groups to overlay onto the stored target, everything
else keeps its persisted value, and unsupported groups (proxy, healthcheck,
edge, edgeSyncBeforeExpiry) fail loudly. Credentials updates are skipped for
site-replication peer targets — probed by both scheme derivations of the
stored endpoint and the stored deployment id — because an operator never
knows the site replicator's credentials, and a body-supplied deployment id
is ignored on update since it anchors peer identity. madmin JSON aliases
(bandwidthlimit, storageclass, resetID, deploymentID, sessionToken) let mc
bodies parse under deny_unknown_fields.
e2e: cover a credential-free sync-only update preserving the stored
connection and the zero-ops no-op contract; align the missing-arn assertion
with the earlier validation error.
* chore(scripts): add two-site replication lab manager
site_replication_smoke.py spawns and manages two local rustfs processes,
pairs them via the site-replication admin API (idempotent), and verifies
bidirectional object replication. Subcommands: up/down/restart/status/logs/
smoke/info/remove/clean. Stdlib-only; requests are SigV4-signed the same
way as crates/e2e_test.
* chore(scripts): rename direction-suffixed payload variables for typos check
The typos linter reads the _ba suffix in payload_ba as a misspelling of
"by"; use payload_a_to_b / payload_b_to_a instead.
